Crypto derivatives platform Delta Exchange announced Wednesday that it has launched futures trading on Solana (SOL) and Cardano (ADA), giving investors a new access point to the leading altcoins. The initial rollout of SOL and ADA call and put options will have daily maturities, with weekly and monthly maturities to be made available at a later date. Options give owners the right, but not the obligation, to buy or sell a specific security at a specified price within a pre-defined timeframe. Call and put options are used heavily in traditional markets but have become more prevalent within crypto markets.
